ment may be provided for each instrument, `the `movable pads connected together,elech trically o1` mechanically and their operation Controlled by some master means, either mechanical or electrical, and in this Way it is possible to obtainfabsolutely simultaneous readings of any number of instruments.

InA the accompanying drawings I have shown one form of attachment which illustrates the object of rny invention.

In these drfmfings--Figure l is e front View of a meter with my attachment in place, the front inelosing casing of the meter being removed; 2 is e side View of the meter shown in Fig. l, the frontfinclosing casing boing in place but broken away to show the interior parts; Fig. 3 is a sectional'yiew teken on line 3-3 of Fig. 2; Fig. 4 is a sectional View teken on line 4--4 of'Fig. 2, and Fig. 5 is e sectionalv Vier-V taken on line 5- of Fig. l. f

The instrument here shown is en electric .Wa'ttmeten rihe measuring element or Ineter disk l is mounted' on 'the spindle I? which may he suitably journaled in e lower been ing 8 and any form of lippe bearing (not shown). The spindle may s eonneeted, .in any well known manner t ,figli gear trains with any number of dial shaftse, four of suchl dial shafts being shown iii-this instrument. In the ordinary meter these dial shafts ter.- -minate in pointers, end concentric with these 'ointers are indcatin' scales ainted orprinted on e dial plate. lf my record attaclune'nt, however, is used in connection With. the instrument. the diei. plate and pointers ere removed and e disl; 5 is secured to the end of each of the shafts et.: Each disk has a hul: 3 adapted for screw-threaded or other eneagjeinent with the end of the corre- .spondinI from the disk vat its center is a point or pin. 7, While near. the edge of each disk is a second point or pin S, the apices of all the pins lying in the saine plane. As the measuring ele ment 3. rotates the various disks will rotate,

to the center of 'the disks and four yotherl -pererarions sltnsted in various Ygessitiene` 1f e tren@ iarentstrip et paper having dials painted Y neon he pissed ever the perforated etrijo-` about' the center peri'oretions.

with the centers of the dials coinciding with the center perforations, the other perfora-V tions will indicate on the dial the reading of the instrument at the time the impressions were made. 'lhis would-be a simple Way of obtaining direct and accurate readings.l I prefer, however, to provide more practical means for adapting the recordv aperto be moved to receive an imprint of t e readings. I, therefore, provide a rectangular frame or shell 9 supported at its center at the end of a rod 10 which rod passes through and is` supported by a frame or plate 11. In this frame is the plate or pad 12, and in the front wall of the frame 9 is cut the opening 13, leaving a rim 14 for holding the'pad 12 in place. 'lhe thickness of the pad 12 alon Aits front and lower edges is equal tothe dept of the frame 9, but the remainder of the pad is thinner, so as to form upper and lower retaining slots 15and 16 into which a record paper, strip 17 may be inserted, the ends of the frame 9 beingopen for this purpose.

' lhe pad 12 may be of soft material to renv ceive the points? and 8, or, as shown, may be of hard substance, such as metal, with a row of central grooves'or holes 18 placed in line with the center pins 7 and with annular grooves 19 concentric with the center pins and opposilte'jthecuter pins 8, the .record paper being 'dspscd in the frame 9 and against the face bfthe pad over the grooves 18 and 19. 'lhe pms will pass through the record paper and into these grooves when the rod 10 is moved inwardly to carry the lpad frame -toward the disks, and when the pad frame 1s again pulled away, the record paper may be withdrawn from the pad frame and will have perforations which exactly indicate theA position of the indicating pins when the impression was taken.

lhe frame 11 is provided with the U- shaped pieces 20 secured thereto by screws 21, anni; the front vplate 22 of the gearing housing of the meter has secured thereto the U-shaped pieces 23 by means. of screws 24,

:said U-shapedpieces bein disposed to pass over and to receive the lim s of the U-shaped pieces 2O of theattachment, and when in such osition the engaging U-shap'ed piecesmay e secured together by screws 25 passing lthrough the upper limbs thereof, and thus the recording` attachment is held rigidlyto the gearing housing with the pad frame opposite the point disks. Guide pins 26 extend from the pad frame and pass through the frame 11 to prevent displacement or rotation of the pad frame. Instead of inserting a piece of record paper, a long strip of record paper may be inserted in the pad frame and fed therethrough for each impression, and to receive the ends of the record strip, drums 27 and 28 may be provided, as best shown in Figs. 1 and 2, one at each end of the plate 11.

For supporting.

the drums, 4U-shaped frames 29 and 30 are provided, each frame having in its upper imb a circular bearing h ole 31 and a slot 32 leading thereto from the edge of the limb, said slot being slightly narrower than the diameter of the bearing hole. The lower limb of each U-shaped frame'has the bearing hole 33, and. the-'end of this lower limb is slightly bent downwardly, as shown.- The lower parts 34 of the shafts of the drums have a diameter equal to the diameter of the lower bearing holes 33 and the width of the slots 32, while the upper arts 35 Aof the shafts have a diameter e ua to the diameter of the upper bearing ho es 31, the arrangement belng such that when a drum is inserted in a U-shaped frame, the lower end of the drum shaft may be inserted in the lower bearing hole 3 3, and the up er end of the shaft part 34 slid through the s ot 32 andl into the upper bearing hole 31 whereupon the drum is dropped to rest on the lower limb of the U- shaped frame and the thicker part 35 of thev drum shaft will enter the bearing hole 31, and veach drunrwill thus be locked in its U- frame. Either' drum may act as the intake drum to receive the paper after its passage through the pad frame from the supp y drum;` The upper ends of the drum shafts may be provided with knurled thumb heads 36 whereby the intakevdrum may be readily turned to advance the record paperaftcr each actuation of the pad frame to take a reading. The ends-'37, 38 of the front wall of the pad frame may be curved toward the drums, as shown in ldigs. 1 and 4, to assist in guiding the record paper. if a reading is desired at certain intervals or times, one of the drum shafts may also be connected with time clock mechanism 39 of any construction and. so arranged that at tne required time it will cause rotation of the drum to advance the paper for each operation of the pad frame to receive a reading.

It is often very desirable, particularly in l making tests, vto obtain simultaneously the readings of a great number of instruments, and with .-my attachment this can be readily accomplished by connecting together' all the pad supporting and actuating rods 10, either mechanically or electrically. If they are connected together mechanically, a single actuation will cause simultaneous move ment ofthe pad frames to simultaneously receive readings from the various instruments. i.

.l have, hcwever, shown electrical means for accomplishing such simultaneous actuation of any number of pad frames. At the end of the rod 10 is secured an armature disk 4Q disposed opposite the electromagnet frame il supporting the energizing winding 42, v

current flowing through this winding causing magnetizing of the frame and attraction of the arnurture4 disk 40 thereto, the result being movement of the pad frame against the indicating pins 7 and 8. To release the armature after cessation of current flow, spring 43 is 'provided encircling the rod and bearing against the armature 40 and the end wall of the pocket 44.v The electromagnets ofthe various instruments may be connected in .any manner'with'a main current supply .g circuit which is controlled by a master man "fal'or automatic means',- suen as an ordinary- 10 electric switch or timeY clock controlledV 's'vvit '5h,I and upon operation. oi'such'master means the various;l electromagnets are si.-l

multaneously actuated andthe' record pads 4 movedsimultarieousl-yto receive'the. records -from the inst ments. After each actuation of the electromagnetsf vtliejrecord' paper in each pad frame may be shifted manually, or

automatically shifted" when the vautomatie' V y `timemechanism 39 is employed on the drum shafts.`

i To identify. the various records on the:

recordl sheet, thatlis, to show' by hich in-` strument .any particular .'record s made, there is provided for each instrument some means, forprinti orindicating on the record sheet the num` er or other character representing the instrument when the pad .frame is moved to receive the record.' I

have'shoWn `the plate 45 secured to the front' wall 220i the gearing train-casing, and from 40 certained by placing over the impressions a plate of glass or other transparent material on which are 'painted or printed the dials Whose centers register with those of the point disks on the meter. l I do not wish to be limited to the particular class of meter or the particular construction 'and arrangement of my attachment here shown, as my invention is applicable to any instrument in which a movable element is connected With indicating or registering dial pointers. The articular' arrangement is one' of lmany Whio 1 could be employed to carry out my invention. t What I claim as new and desire to secure by Letters Patent is:
